Is there a way to complete “paste with original style” or equivalent of menu command (⌥⇧⌘V) instead of “paste” (⌘V) by applescript
example copy/paste from Safari to OO:

tell front document
set last_row to row -1
set topic of last_row to (get the clipboard as string) -- > simple paste
-- or
set topic of last_row to (get the clipboard) -- > simle paste
-- or
set topic of last_row to do shell script "pbpaste" -- > simle paste
-- or
set topic of last_row to (get the clipboard as record) -- > OmniOutliner got an error: Can’t make {«class weba»:«data weba6262706C6973743030D10 ... etc}
end tell

so with (end of ...) it makes multiple rows if I copied several lines and
I can’t change topic’s value of existing row

pbpaste at topic of row -- return_error_as_expected
end

In other words (pbpaste) makes new location and can’t change the existing? I got this right?
If it so…
How to get the value of pbpaste (clipboard) as “original style” instead of string?
Is there any other way to handle this command pbpaste?
I’ll think further about it…

pbpaste mimics the behaviour of menu command paste with original style, I think. If you copy some text and click that menu item, it will create new row(s) below child collection. It will not overwrite existing and does not return any value.

If you tell me more about what your specific use case, maybe I come up with a solution.

Yes, I’m understanding. Thanks for the reference.
So I can’t assign object specifier to a variable, or return it as a value.
It’s apparently the reason for that pbpaste makes multiple row if I copy more than one line.

My routine tasks are copy/paste from Safari to Outliner’s row topic.
But each line of clipboard are becoming as the new object by pbpaste. And I expect from this copy/paste that it will be paste into the topic of single row.

expectations - if I copied inside the Safari and pasted inside the OO:
the result by (pbpaste) - if I copied inside the Safari and pasted inside the OO:

probably I’ll have to merge created rows into the single row
p.s. But If the copy was made inside the OmniOutliner then the command of pbpaste do the paste by one row.
